Trait Implementations

impl Clone for UnOp

fn clone(&self) -> UnOp

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for UnOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for UnOp

fn eq(&self, other: &UnOp) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<UnaryOperator> for UnOp

type Error = ExprError

The type returned in the event of a conversion error.

fn try_from(op: UnaryOperator) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for UnOp

impl StructuralPartialEq for UnOp
